-LRB- CNN -RRB- -- Defending champions Spain are through to the 2012 Davis Cup final after a 3-1 defeat of the United States .

Spanish world No. 5 David Ferrer beat John Isner 6-7 -LRB- 3-7 -RRB- 6-3 6-4 6-2 in Sunday 's decisive singles match in Gijon , after brothers Bob and Mike Bryan had kept U.S. hopes alive with victory in Saturday 's doubles match .

Spain will appear in the final for the sixth time in the last 10 years as they bid for a sixth Davis Cup triumph .

The win extends Ferrer 's perfect record in clay-court Davis Cup singles rubbers . The 30-year-old has won all 16 of his matches on the surface .

`` I 'm very happy , this is a dream for me , '' Ferrer told the tournament 's official website . `` Another Davis Cup final , we won here at home in Gijon .

`` I won the last match against John Isner , who is a very good player , and this tie was never easy .

`` The atmosphere was unbelievable . They supported me all the time in the match . I want to enjoy this moment , I 'm really happy . ''

Injury robbed Spain of 11-time grand slam winner Rafael Nadal , who is struggling with a knee problem .

The final will be a repeat of the 2009 showpiece after Tomas Berdych 's straight-sets win against Carlos Berlocq saw the Czech Republic seal a 3-1 victory over 2011 runners-up Argentina .

World No. 45 Berlocq was drafted in for the singles match after Argentina 's No. 1 Juan Martin del Porto was forced to withdraw from the tie through injury on Saturday .

Berdych , a semifinalist at the recent U.S. Open , was rarely troubled by Berlocq and sealed a straight-forward 6-3 6-3 6-4 win , much to the disappointment of the Buenos Aires crowd .

The Czech Republic will have home advantage for the final , which will take place between November 16-18 .
